Holmes is recast as a kind of Victorian James Bond, both in terms of his character and the plot structure. It begins with the end of the previous mission, before progressing through various familiar beats, like the villain helpfully explaining his plan and a climactic big shoot-out... except on a much, much, much smaller scale. To add to the effect, Dr Watson is revealed to be “a bit of an inventor” — a Q in the making? Even Holmes himself is not immune: young, dashing, and womanising. Yes, womanising.
